Product Information
The SMT172 is a three terminal integrated temperature sensor with a duty-cycle output. Two of the terminals are used for the power supply (2.7 -5.5 Volts) and the third terminal carries the output signal. A duty cycle modulated output is used so that the output can be read by a microprocessor, while the analogue information is still available.
The sensors are available in a number of encapsulations: TO18, TO92, TO220, SOIC-8L, SOT223, HEC and in a 7 mm ss. probe with 5 mtr cable. The SMT172 can be supplied as a naked die as well.
The SMT172 has an overall accuracy of 0.1 °C in the range from -20 °C to +60 °C and an accuracy of 0.4 °C from -45 to +130 °C. This makes the sensor especially useful in all applications where human conditions (climate control, food processing etc.) are to be controlled. The CMOS output of the sensor can drive cable lengths up to 20 meters. This makes the SMT172 very useful in remote sensing and control applications.
